IMPROVEMENT lN, WASH-BOARDS.

Specification forming part of Letters Patent No. 219,053, dated August 26, 1879; application filed March 11, 1878.

To all whom it mag concern:

Be it known that I, HENRY S. WILLIS, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Wash-Board, of which the following is a specification.

Figure 1 is a front elevation of my improved wash-board. Fig. 2 is a transverse section taken on line 00 w in Fig. 1.

Similar letters of reference indicate corresponding parts.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

The wash-board maybe made of any of the materials from which wash-boards are ordinarily made, (such as wood or zinc,) and its face A, which is corrugated or provided with transverse ribs 0, is formed in a recess on a double-reversed curve, a b, the middle of the board being outwardly convex, while the portion lying between the convex middle portion and the edges are concave. The extreme edges project nearlyat a right angle with the plane of the board, and are considerably more prominent than the middle convex portion of the board.

The transverse corrugations or ribs 0 traverse entirely the bottom wall and both the side walls'of the recess in which the rubbingsurface is located, so that the rubbing of the clothes is made entirely against corrugated surfaces, and there is no loss of labor, as when the side walls of a wash-board present smooth surfaces, the rubbing contact of which with the clothes has no cleaning effect.

I am aware that a wash-board having a concave or recessed rubbing-surface has long been known; but I am not aware that the inner surfaces of the side walls of such a washboard have been traversed by extensions of the corrugations, so that the clothes being washed will come in contact only with a corrugated surface.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 7 1. A wash-board having its rubbing-face formed in a recess the bottom wall and both side walls of which are entirely traversed by transverse corrugations, substantially as and for the purpose set forth.

2. A wash-board having its rubbing-face formed in a recess the bottom wall and both the side walls of which are entirely traversed by transverse corrugations formed on doublereverse curves, the ends of said corrugations projecting above, or in front of, the plane of the middle of the board, substantially as described.

HENBY S. WILLIS.
